I'm not registed user on wyBuild but i've found bug.
If you will try to activate wyBuild (my friend gave key to me because i wanted to test it after 14 days of trial) on 64 bit system when after you enter the key hresult 0x8007000B error appears, i think it means that app trying to load 32 (or 64) bit dll in 64 (or 32) bit application
That's definitely a bug. It will also effect delta patch creation. Thanks for pointing it out.

That's technically piracy, Alex. If you want to test wyBuild for more than 14-days then you can e-mail us and we will send you an extension key.
Also, the 14-day trial is for 14-real days of use. For example, you can use wyBuild for 1 day in each month and still have 2 trial days left. So, in many cases 14-day should be more than enough.
But thanks for notifying me of the bug. It'll be fixed in the next version.
